From 3119cbda858fc9ae10a69919e5f278abd6d93bb5 Mon Sep 17 00:00:00 2001 From: Jamie Iles Date: Tue, 11 Jan 2011 12:43:50 +0000 Subject: [PATCH] mmc: jz4740: don't treat NULL clk as an error clk_get() returns a struct clk cookie to the driver and some platforms may return NULL if they only support a single clock. clk_get() has only failed if it returns a ERR_PTR() encoded pointer.
